Application filed August 3, 1905. Serial No. 272,605.

To all whom it may concern:

Be it known that 1, CHARLES 'Srino, citizen. of the United States, residing at New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Margin- Steps, of which the following is a specification, reference being had therein to the accompanying d awmg.

This invention relates to a typewriter and particularly to a construction comprising margin gage devices and other cooperating parts.

An object of the invention is to provide means by which a margin stop mechanism may be capable ofindependent movements successive to each other whereby a secondary stop may be thrown in the path of the con tact after the first is removed therefrom and a longitudinal. movement of. the stops bodily effected to operate a line locking (lOVlCi 0th: and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings, Figure 1, is a plan of the machine; Fig. 2, a side elevation thereof.

with parts broken away to indicate the shifting cradle; Fig. 3, a rear elevation with parts broken away; Fig. 4, a plan of the bar lock; Fig. 5, an elevation of the key'projcction to engage this look; Fig. 6, a side elevation of the operating keys for the margin'stops; Fig. 7, a perspective of these keys; Fig. 8, a detail perspective of the margin stop mechanism in normal position; Fig. 9, an elevation of this mechanism when shifted to operate the line lock Fig. 10. a vertical section of the margin stop in the position shown in Fig. 9; F 11, a similar view with the secondary stop in engagement-with the contact; Fig. 12, a like view with both of the stops therein clear of the contact; F 13, a detail perspective of the means for securing the interchangeable carriage upon the cradle, and Fig. 14: is a like view of the bell ringer.

Like letters of reference refer to like parts in'the several figures of the drawings.-

The letter A designatesthe frame of the machine which is provided with the usual key A and type levers A at the key board. thereof. The interchangeable car-- riage A may be of any desired construction and; is provided with the platen A disposed adjacent to the type bar locking device fit opposite sides of this device the usual ribbon mechanism A" is disposed and surrounding these parts the type bar segment A carrying the various type bars B! These bars are each provided with the usual type B at their outer ends, and when used with the shiftable cradle a plurality of such type are carried by each bar. The bar has depending from the typeface thereof lug B having a beveled or chisel point- B adapted to enter one of the series of vertical slots B provided upon the concaved face B of the bar locking plate. The provision of these vertical slots permits the accurate formation of the plate and its disposition closer to the printing point so that a greater number of the slots may be used than can be provided with the ordinary construction of pins. In providing a larger number of these slots they may be disposed in. such alinemcnt with the pivots of the bars as to prevent the side or torsional strain on the bar which commonly occurred when a single bar locking point vas provided and the bar was bent or deflected so as to enter this point.

The interchangeable carriage A is removably secured in position upon the cradle C in any desired manner, for instance, one of the end frames A of the carriage base having the back bar A?" may be provided with a slot or recess A. 'in its outer face which .is adapted to engage the segmental head C of the screw C which is mounted upon the cradle C of the machine. it will be seen that when the head C is disposed within the slot, as shown in Fig. 13, the carriage base will be firmly retainedto the cradle. When the screw is turned so as to bring its flat face C opposite the slot of the carriage base, the carriage may be readily removed from the cradle. This cradle is pivotally mounted to the frame of the machine, as shown at G, and may be operated in any desired manner, for instance, by means of the key lever C attached to the cradle and the restoring spring C extending from the cradle to a fixed point upon-the frame. This use of an interchangeable carriage upon a shiftahle cradle adapted to cooperate with type bars carrying a plurality of type provides means by which any desired length of carriage and platen may be used in connection with the machine for different classesof work, for instance, as is necessary in tabulating upon large sheets of paper.

.faee with a scale D of the usual character which the contact blocks may be adjusted and the paper guided into the machine. The finger portions of the blocks cooperate with said scale toindicate the position of the blocks relative to the rack bar.

The carriage is mounted upon the frame of the machine in any desired manner, for instance, by means of the roller bearings A disposed between the same and a back bar A carried by the frame. This back bar also supports the margin stop mechanism E.

The stop mechanism E is provided with a primary stop E and a secondary stop E disposed when at rest in a lower horizontal plane from the primary stop. These stops are pivotally mounted to swing away from the contact blocks D by means of' the ears E at opposite ends of the stop plate which are mounted upon a bearing rod E carried by the ears E at opposite ends of the plate E. This plate is also provided with a horizontally disposed contact face E for the primary stop E and with a similar face E for the secondary stop E ,'while an abut-- ment wall E is disposed at one end of the face E and a similar wall E at the opposite end of the face E both of these walls being out of alinement with the block D These faces provide a sliding contact surface for the stops in their longitudinal movement with the carriage after the primary engagement of the contact block therewith and the stops may be restored to their normal position after being released from the carriage by means of the coil s )rin E surroundin v A?) h the rod E and disposed between the ears E and it) at one end of the mechanism. De- [)Clitllllfgfdl'txll'! the stop plate is a finger F having an extension F therefrom disposed at an angle to the vertical plane of the finger, as shown in Fig. 10. This extension upon its inclined wall face engages the locking hook 1 adapted to engage the universal hail l for locking all of the key levers at the end of the line. The locking hook F is pivoially mounted at F and is normally held wilh its hooked end F removed from the sovlwl F in the universal bail by means of lcnsiou spring F suitably mounted upon a relatively fixed part of the frame, while the upper angularly disposed end of the hook is provided with a curved contact face F with which the extension 1 enga when. the margin stops are thrown upward, thus forcing the line lock hook into contact with the universal bail.

The abutment wall E is inclined upon its face next the secoi'idary stop E so that in the longitudinal movement of the stops the secondary stop rides upward thereon thus automatically moving the primary stop E out of the path of the contact block or from the position shown in Fig. 10 to that of Fig. 11, and this occurs during the line locking action of the parts.

For the purpose of operating a bell ringer mechanism Gr in the step by step travel of the carriage the contact block is provided with a depending pin G adapted to engage a V-shaped striker G pivotally-mounted at G upon the back bar A. of the machine. This striker mechanism is provided with a depending arm G carrying a restoring; spring G having its free end extended through a loop G. The arm G'* is provided with a finger G adapted in its oscillation to strike the projection G carried by the pivoted lever G held under spring tension and adapted to engage the bell G in the operation of the machine. This bell ringer may be of any desired construction, that herein shown in Fig. 14 being a convenient and desirable form for the purpose.

For the purpose of oscillating the stop mechanism for different degrees of travel in order to throw either of the stops into the path of the contact block a key lever H- provided and extendsto the key board of the machine where it provided with the usual key H which in its operation constitutes a margin lever and throws the stops entirelyclear of the contact block. This lever H is pivotally mounted at the rear of the frame, as shown at H and is connected to a rock lever H pivoted at H by means of a link i 5 pivotally connected at H to said rock lever. The opposite end H of the rock lever is provided with a suitable beveled or inclined contact face H adapted in its travel to engage the member 1" and force the same inward, thus raising the stops and throwing the line lopk into engagement with the universal bail. When it is desired to raise the stops for only a portion of thbir travel so that the primary stop may be clear of the contact block and the secondary stop interposed in its path this margin lever is only depressed for a portion of its travel, which is accomplished by means of a aragra1 )h key I pivotally mounted at 1" upon the margin lever and provided with a yoke I extending over said lever and having a socket I at its lower portion with which the margin lever engages at the extreme of its downward movement. This paragraph key is disposed above a portion key or lever upon the margin lever permits a continued movement of the latter when it is desired to disengage the secondary stop from the abutment block.

In the operation of the invention the means for mounting the interchangeable carriage provided with the rack and contact blocks disposed thereon permits the removaland changing of the carriage independent of the remainder of the machine and without in anywise affecting the same as either a long or short carriage may be used as found most convenient or desirable for the class of work to be performed. These contact blocks are disposed at opposite sides of the stop mechanism so as to allow both tocooperate therewith and determine the opposite margins upon the bar. In the travel of the carriage from right to left by the ordinary step by step feed the contact block at the right of the stop mechanism first engages the bell ringer sounding the usual warning. before reaching the end of the line and then by contact with the primary stop shifts the stop plate longitudinally upon the rod and its extension throws the line look into engagement. If it now be desired to add additional letters or words to the line already written space for this purpose may be provided by depressing the paragraph key which oscillates the stop mechanism sufficiently to raise the primary stop out of the path of the block and interpose the secondarysto'p in. its path, allowing an additional number of spaces in this manner. If for any reason it be desired to entirely remove the stops the margin lever will be pressed downward. so that the writing may be ex tended into the margin at that side of the paper. In the return of the carriage to its initial position for beginning another line the block at the left thereof passes over the secondary stop and engages the primary stop which establishes the uniform margin onythe paper, but under some conditions such as paragraphingit is desired to leave a greater space at the margin and the paragraph key is then depressed which raises the secondary stop into the path of the contact block. It will be seen that the engagement of the margin lever and paragraph key provides means for oscillating the stop mechanism for different lengths of travel and this mechanism cooperates with each of the contact blocks to control the margins at both sides/of the paper. The stop mechanism normally lies with the primary stop in the path'of the contact block and is adapted for alongitudinal lIlOVGlLcuL, a partial elevation, and a complete elevation.
